Written ByHoward Parker

As aquarium keepers, we pour our hearts into creating vibrant, balanced underwater ecosystems. We understand the delicate dance of light, water, and life. But have you ever felt the urge to apply those skills above the water line, to craft a miniature, self-contained world of green you can hold in your hands?

I know that feeling well. The good news is that your aquascaping experience gives you a huge head start. This guide promises to show you exactly how do you make a terrarium in terraria, translating your aquatic knowledge into a stunning piece of living, breathing art for your home.

We’ll walk through everything, from choosing the perfect container and plants to mastering the art of layering and long-term care. Get ready to create a tiny green paradise that perfectly complements your aquatic passion.

Why Every Aquarist Should Try Building a Terrarium

You might be wondering what a jar of plants has to do with your aquarium hobby. The answer? Almost everything. The principles are beautifully intertwined, making this a natural and rewarding next step for any aquarist.

One of the biggest benefits of how do you make a terrarium in terraria is understanding a different kind of ecosystem. Just like a cycled aquarium, a closed terrarium creates its own water cycle. Moisture evaporates, condenses on the glass, and “rains” back down on the plants. It’s a fascinating, hands-on biology lesson.

This project is also a fantastic way to practice principles of composition and planting that directly translate to aquascaping. You’ll be thinking about focal points, textures, and color, all on a manageable scale. Plus, it’s an incredibly eco-friendly how do you make a terrarium in terraria project; you’re creating a tiny, sustainable biosphere.

Gathering Your Supplies: The Terrarium Builder’s Checklist

Before we get our hands dirty, let’s gather our materials. Think of this like setting up a new tank—getting everything ready beforehand makes the process smooth and enjoyable. You don’t need much to get started!

The Perfect Vessel: Glass Containers

Any clear glass container with a wide enough opening for your hand will work. Old jars, vases, or even a classic fishbowl can be repurposed beautifully. For beginners, I recommend a container that is at least one gallon in size to give your plants room to breathe.

  • Closed Terrariums: Jars with lids or corks are perfect for humidity-loving tropical plants.
  • Open Terrariums: Bowls or vases without lids are ideal for arid plants like succulents that need airflow.

The Foundation: Drainage and Substrate Layers

This is the most critical part, much like the substrate and filter media in your aquarium. A proper foundation prevents root rot and keeps your ecosystem healthy.

  • Drainage Layer: Small pebbles, gravel, or LECA (lightweight expanded clay aggregate).
  • Filtration Layer: A small piece of mesh (like a window screen) and a thin layer of activated charcoal. Yes, the same stuff you use in your filter! It keeps the environment fresh and fights bacteria.
  • Substrate Layer: A high-quality potting mix suitable for your chosen plants. For tropicals, a peat-based mix is great. For succulents, a sandy, well-draining cactus mix is essential.

The Stars of the Show: Choosing the Right Plants

Select small, slow-growing plants that share similar light and humidity requirements. Don’t crowd the container; give them space to grow into their new home.

The Finishing Touches: Tools and Decorative Elements

Long tweezers or chopsticks are your best friends for placing plants in tight spaces. A small paintbrush can help clean soil off leaves and glass. Feel free to add small stones, moss, or driftwood to complete your miniature landscape—just like in your aquarium!

The Ultimate Guide: How Do You Make a Terrarium in Terraria Step-by-Step

Alright, let’s build this thing! This how do you make a terrarium in terraria guide breaks down the process into simple, easy-to-follow steps. Don’t rush it—enjoy the creative process.

  1. Clean Your Container: Start with a sparkling clean canvas. Wash your glass container thoroughly with soap and hot water, then rinse well and let it dry completely. Any lingering bacteria can cause problems later.
  2. Add the Drainage Layer: Pour in a 1- to 2-inch layer of your chosen gravel or pebbles. This creates a reservoir for excess water to collect, keeping it away from the plant roots and preventing rot. This is one of the most important how do you make a terrarium in terraria tips!
  3. Add the Filtration Layer: Cut a piece of mesh to fit the container’s diameter and place it on top of the gravel. Then, add a thin (about half an inch) layer of activated charcoal. This layer prevents soil from mixing into your drainage and keeps the terrarium smelling fresh.
  4. Lay the Substrate: Add your chosen potting mix. You’ll want a layer that’s deep enough for your plants’ roots to establish themselves, typically 2-3 inches. Gently slope the soil to create a more natural and visually interesting landscape.
  5. Time to Plant!: This is the fun part! Gently remove your plants from their nursery pots and tease the roots apart. Use your fingers or tweezers to dig a small hole in the substrate, place the plant inside, and gently pat the soil around its base. Start with your largest “focal point” plant and work your way down.
  6. Decorate Your World: Once your plants are in place, add your decorative elements. Tuck in some sheet moss between plants, place a few interesting stones, or add a small piece of spiderwood. Let your inner artist out!
  7. The Initial Watering: Give your terrarium its first drink. Use a spray bottle or a watering can with a narrow spout to gently water around the base of the plants. You want the soil to be moist, not waterlogged. For a closed terrarium, you should see light condensation on the glass within a day.

Choosing Your Terrarium’s Inhabitants: Plant Selection Made Easy

Choosing the right plants is the key to a long-lasting, low-maintenance terrarium. It’s just like stocking a community tank—you need inhabitants that thrive in the same conditions. Here are some fantastic, beginner-friendly options.

For Closed Terrariums: High-Humidity Lovers

These plants adore the moist, humid environment of a sealed container.

  • Nerve Plant (Fittonia): Known for its striking veined leaves in pink, red, or white. It loves humidity but can be a bit dramatic if it gets too dry!
  • Small Ferns: Maidenhair ferns or bird’s nest ferns look beautiful and thrive in the enclosed moisture.
  • Mosses: Cushion moss or sheet moss is perfect for creating a lush, green carpet.
  • Baby’s Tears (Soleirolia soleirolii): A delicate, creeping plant that quickly forms a dense, beautiful mat.

For Open Terrariums: Arid & Sun-Loving Plants

These plants need good airflow and drier conditions, making them unsuitable for closed containers.

  • Succulents: Echeverias, Haworthias, and Gasterias come in countless shapes and colors.
  • Cacti: Small cactus varieties add wonderful texture, but be careful with their spines during planting!
  • Air Plants (Tillandsia): These don’t even need soil! You can simply nestle them on top of sand or amongst some driftwood.

Plants to Avoid

Steer clear of fast-growing plants that will quickly outgrow the container, plants that require direct, intense sunlight (the glass can scorch them), or any flowering plants that will drop petals and create a mess.

The Terrarium Care Guide: Keeping Your Miniature World Thriving

You’ve built your masterpiece! Now what? Fortunately, a well-built terrarium is incredibly low-maintenance. This how do you make a terrarium in terraria care guide will help you keep it looking great for years.

Lighting: Finding the Sweet Spot

Your terrarium needs bright, indirect light. A spot near a north-facing window is often perfect. Direct sunlight will act like a greenhouse, cooking your plants. If you notice your plants are stretching or pale, they may need a bit more light.

Watering: Less is More

This is the #1 rule. Overwatering is the fastest way to kill a terrarium. For a closed terrarium, you may only need to water it every few months, or even less! If you see heavy condensation on the glass all day, crack the lid for a few hours to let it air out. For open terrariums, water only when the soil is completely dry to the touch.

Pruning and Maintenance

Following how do you make a terrarium in terraria best practices includes regular check-ups. Trim any yellow or dead leaves to keep the terrarium healthy and clean. If plants get too large, you can prune them back to encourage bushier growth and maintain the scale of your design.

Troubleshooting: Common Problems with How Do You Make a Terrarium in Terraria

Even with the best care, you might run into an issue or two. Don’t worry! Most problems are easy to fix. Here’s how to handle the most common ones.

Problem: Mold or Fungus

Cause: Too much moisture and not enough air circulation.
Solution: Remove the visible mold with a cotton swab. Leave the lid off your terrarium for a day or two to let it dry out, and reduce your watering frequency going forward.

Problem: Yellowing or Droopy Leaves

Cause: This is almost always a sign of overwatering and root rot.
Solution: Immediately stop watering. If the soil is soggy, you may need to leave the lid off for several days. If a specific plant looks beyond saving, it’s best to remove it to protect the others.

Problem: Foggy Glass (Too Much Condensation)

Cause: The water cycle is a bit too active.
Solution: This is a simple fix! Just remove the lid for a few hours until the excess condensation clears. A little bit of morning and evening fog is normal and healthy.

Problem: Pests (Gnats, etc.)

Cause: Pests can hitch a ride on new plants or in potting soil.
Solution: Isolate the terrarium from other plants. You can often control fungus gnats by letting the top layer of soil dry out completely between waterings. Sticky traps can also be effective.

Frequently Asked Questions About How Do You Make a Terrarium in Terraria

How often should I water my closed terrarium?

It varies, but a properly balanced closed terrarium can go for months or even a year without needing water! The key is to watch the condensation. If you see a light mist on the glass in the morning that clears by the afternoon, your water cycle is perfect. If you never see condensation, it might be time for a few spritzes of water.

Can I add insects or small animals to my terrarium?

This is called a vivarium and requires a much more complex setup. For a simple decorative terrarium, it’s best to stick to plants. Adding critters like isopods (rolly-pollies) or springtails can be beneficial as a “clean-up crew,” but larger animals have specific needs that a small jar cannot meet.

Why is activated charcoal so important in a terrarium?

Think of it as your terrarium’s chemical filtration. In a closed, damp environment, organic matter can break down and create odors and harmful bacteria. Activated charcoal is highly porous and absorbs these impurities, keeping the soil and air fresh and clean for your plants.

What’s the main difference between an open and closed terrarium?

A closed terrarium has a lid and creates a high-humidity, self-watering ecosystem ideal for tropical plants like ferns and moss. An open terrarium has no lid, allowing for much more airflow and lower humidity, which is necessary for arid plants like succulents and cacti that would rot in a closed environment.

Your Miniature World Awaits

See? Your skills as an aquarist have prepared you perfectly for this journey. You already have an eye for creating beautiful, balanced environments and an understanding of how delicate ecosystems work.

Building a terrarium is more than just a craft; it’s an opportunity to create a peaceful, living sculpture for your home. It’s a quiet counterpart to the vibrant motion of your aquarium, offering a different kind of natural beauty.

Now you have the complete guide and all the tips you need. Go find a beautiful glass jar, get your hands a little dirty, and bring a tiny, thriving world to life. Happy building!
